Calculating the Number of Students on Chekhov Street

To calculate the number of students living on Chekhov Street, we can use the given fractions of students living on different streets and the total number of students in the class.

Given: - Total number of students in the class is less than 50. - Fraction of students living on Tverskaya Street: 1/7 - Fraction of students living on Petrovka Street: 1/3 - Fraction of students living on Malaya Bronnaya Street: 1/2 - Remaining students live on Chekhov Street.

Let's calculate the number of students living on Chekhov Street.

Solution

To find the number of students living on Chekhov Street, we can use the following steps:

1. Calculate the total fraction of students living on Tverskaya, Petrovka, and Malaya Bronnaya Streets. 2. Subtract this total fraction from 1 to find the fraction of students living on Chekhov Street. 3. Multiply the fraction of students living on Chekhov Street by the total number of students in the class to find the actual number of students living on Chekhov Street.

Calculation

1. Total fraction of students living on Tverskaya, Petrovka, and Malaya Bronnaya Streets: - Fraction on Tverskaya Street: 1/7 - Fraction on Petrovka Street: 1/3 - Fraction on Malaya Bronnaya Street: 1/2 - Total fraction: 1/7 + 1/3 + 1/2 = 17/42

2. Fraction of students living on Chekhov Street: - Fraction on Chekhov Street = 1 - 17/42 = 25/42

3. Calculate the number of students living on Chekhov Street: - Total number of students in the class is less than 50. - Number of students on Chekhov Street = (25/42) * Total number of students

Let's calculate the exact number of students living on Chekhov Street using the given information.

Answer

The number of students living on Chekhov Street can be calculated using the above steps. The exact number of students living on Chekhov Street will depend on the total number of students in the class, which is not provided in the given information.
